The ASP.NET MVC TreeView control provides built-in support for checkboxes, allowing users to select more than one item. The tree view checkbox has a tri-state mode also, which is applicable only for parent nodes. In this mode, the parent node will go into the indeterminate state when the child nodes are partially checked.

ASP.Net Core MVC does not have any TreeView class and hence the TreeView will be implemented using the jQuery jsTree plugin. The TreeView will be populated from Database using Entity Framework in ASP.Net Core MVC. Note: For beginners in ASP.Net MVC Core, please refer my article ASP.Net MVC Core Hello World Tutorial with Sample Program example.

CREATE TABLE [dbo]. [Categories] ( I have attached sample SQL query file named “categoryDb.sql” to create table and insert the records.
